Description

Many builders installing the Cummins R2.8 prefer running a mechanical fan but in factory form the R2.8’s fan hub is not very useful. The hub face is far too close to the rest of the engine accessories, and the R2.8’s fan hub bolt circle is also not the same as commonly available fan spacers. The Quick Draw R2.8 Mechanical Fan Kit includes everything you need to run a mechanical fan on the R2.8.

Our versatile  Cummins R2.8 hub kit locates the fan  1″, 1.5″, or 2″ from the fan hub, allowing proper positioning of a mechanical clutch fan with a variety of different radiator spacing. Fan-to-radiator spacing is critical for proper cooling performance, and with many builds radiator positioning and clearance isn’t finalized until late in the build process. Instead of getting locked into one spacer width,the Quick Draw kit offers three positions, enabling builders to get fan and radiator positioning dialed in perfectly. Our kit also includes a Hayden fan clutch and your choice of either a 17″ or 20″ diameter fan

Whats Included:

  • 1″ mechanical fan hub adapter
  • Qty 2 of .5″ thick spacers
  • 3 different height dowels to index themechanical fan clutch
  • Qty 12 different height studs to attach fan clutch to the adapter kit
  • 4 lock washer and nuts
  • Hayden fan clutch
  • Derale 6 blade mechanical fan

How it Works:

Cummins ships the New R2.8 diesel engine with a fan hub that acts as an idler pulley.  Start by removing the 4 bolts and steel spacer, then attach the 1″ mechanical fan hub adapter to the hub using the factory bolts.  Next, without installing dowel pin, hold the fan in the location you wish it to be and measure which of the three provided heights locates it best.  After confirming which spacing works best, install the necessary dowel pin in the adapter with a rubber mallet and install the needed 1/2″ spacers on the dowel.  Place the fan clutch with fan already installed on the four supplied studs,  install the 4 lock washers, and tighten the nuts.
